Comment 4 for bug 1001040

Have circumvented the problem by adding "smtpd_tls_exclude_ciphers = RC4-MD5" to my /etc/postfix/main.cf.

Google is now using RC4-SHA instead, and I've experienced no further problems so far.

Obviously this may not be a postfix bug (it seems openssl-related issues can even be cause by compiler optimization or other issues and it seems likely in any case that the bug is in the openssl library that postfix is using) but I am more than willing to help diagnose it, whatever package it belongs in. It should be 100% reproducible if I stop the cipher exclusion unless google changes something on their end.
